1. A metasurface arrangement comprising a first metasurface and a second metasurface which run mutually parallel and face each other, each metasurface comprising a corresponding periodic or quasi-periodic structure in a respective pattern, wherein the first metasurface is in a dielectric material structure and the second metasurface is in either a dielectric material structure or in an electrically conducting structure, wherein:
the periodic or quasi-periodic structure on the first metasurface is configured to yield a first response to an incident electromagnetic wave between the two metasurfaces, and the periodic or quasi-periodic structure on the second metasurface is configured to yield a second response to the incident electromagnetic wave between the two metasurfaces that is equivalent to the first response, thereby rendering the two metasurfaces mutually electromagnetically symmetric, and
the second metasurface comprises a second periodic or quasi-periodic structure, where each periodic or quasi-periodic structure of the first and second metasurfaces have mutually different geometries rendering the first and second metasurfaces mutually electromagnetically symmetric.
